Automatic adjustable differential pressure regulator

(VT.043.G) VT.043 automatic adjustable differential pressure regulator is designed for maintenance of the preset differential pressure (ΔRn) in the dynamic mode in two-pipe heating and cooling systems with variable flow.

The main purpose of the regulator is combined action with VT.054 balancing valve in two-pipe heating systems. In this case, VT.054 balancing valve sets the design value of the connection differential pressure in the served circuit (ΔDc), while the design differential pressure in this section (ΔPn) is maintained by the differential pressure regulator. In case when use of the balancing valve is not required, it is recommended to connect the impulse tube to the ball valve with drainage and air vent valve VT.245, equipped which nozzles with 1/4 ” female thread (see application examples).

The body of VT.043 automatic differential pressure regulator has nozzles for connection of the electronic device measuring the differential pressure and flow rate on the valve.

The cartridges of the regulator are equipped with a copper impulse tube with M8 x 1/4” adapter (male thread) for connection to VT.054 balancing valve or to VT.245 ball valve.
